The New York City Council has voted to scale back a key tax break for small business owners, trimming the personal income tax credit that offsets the city’s Unincorporated Business Tax. The cut, approved Thursday, is noticeably smaller than what Mayor Zohran Mamdani had pushed for in his executive budget. The measure passed on July 16, takes effect immediately, and is retroactive to January 1, 2026, with Council leaders pitching it as a budget-saving adjustment that still cushions middle-income pass-through owners.
The change comes via Preconsidered Intro No. 972, sponsored by Council Member Linda Lee, which cleared the Council on July 16 by a 56-8 vote. The legislative record lists Lee as sponsor and details the committee action and roll call for the bill. According to Docket.NYC, the measure moved through the Finance Committee and was enacted the same day.
What the law changes
The new local law rewrites the city’s tiered Unincorporated Business Tax credit formula starting with tax year 2026. It keeps a 100 percent credit for residents with city taxable income of $42,000 or less, while dialing the benefit down as income rises. For city taxable income between $142,000 and $1,000,000, the credit will be set at 23 percent for 2026. Once city taxable income hits $1,250,000 or more, the credit drops to 15 percent. The law takes effect immediately and applies retroactively to January 1, 2026, according to Docket.NYC.
How that compares to Mamdani's plan
Mayor Zohran Mamdani’s executive budget had called for steeper cuts to the credit for filers with city taxable income above $142,000. His administration estimated the tougher version would bring in roughly $68 million a year, according to the Mayor's Office. The city comptroller, in separate budget comments, put the annual revenue effect from reducing the Unincorporated Business Tax credit closer to $71 million. Those dueling estimates helped frame the tug-of-war between City Hall and Council leaders during budget talks.
Why the Council scaled back
Council negotiators said they were looking for new revenue to close budget gaps but did not want to hit middle-income proprietors as hard as the mayor’s team had suggested. The final language preserves a larger share of the credit for many pass-through owners than Mamdani’s original proposal would have. The vote was not unanimous, reflecting the political tension over who should absorb more of the city’s fiscal pain. As Crain's New York Business reported, Council leaders cast the package as a compromise designed to balance fresh revenue with protections for smaller businesses and households.
Who’s affected
The Unincorporated Business Tax credit typically goes to roughly 24,000 filers, giving them a break on their city personal income tax based on UBT paid by partnerships or sole proprietors. Under the revised formula, most low- and middle-income proprietors will hang on to a large portion of that credit, while the sharpest reductions land on very high-income filers and large pass-through owners. For the fine print on eligibility and how to claim the credit, the city directs taxpayers to guidance from the Department of Finance and the mayor’s budget materials, including the NYC Department of Finance.
Legal and tax implications
Because the change is both effective immediately and retroactive to January 1, 2026, some taxpayers who already filed 2026 returns may have to revisit their paperwork and possibly file amendments with their accountants. The Council’s local law explicitly makes the adjustment retroactive, and the city’s tax agencies typically follow with administrative guidance and technical corrections in the weeks after a tax change is enacted. Taxpayers with questions are advised to consult professional tax counsel or contact the Department of Finance for specific instructions.
